Study Notes
Overview of SARS-CoV-2
- Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a single-stranded RNA virus.
- Primary mode of transmission is through respiratory particles.
Transmission
- Viral entry into host cells involves the spike protein binding to the ACE2 receptor.
- Immunity is conferred by antibodies targeting the spike protein.
Clinical Presentation
- Disease severity ranges from asymptomatic to critical; most cases exhibit mild symptoms.
-
Common Symptoms include:
- Fever
- Myalgia (muscle pain)
- Headache
- Nasal congestion
- Sneezing
- Cough
- Sore throat
- Gastrointestinal symptoms such as nausea and diarrhea
-
Specific Symptoms:
- Anosmia (loss of smell)
- Dysgeusia (altered taste sensation)
Complications
- Pneumonia is the most frequent serious complication observed.
- Hypercoagulability can lead to thromboembolic events such as:
- Deep vein thrombosis (DVT)
- Pulmonary embolism (PE)
- Stroke
- Other severe complications include:
- Acute respiratory distress syndrome (ARDS)
- Myocardial injury (heart damage)
- Neurologic issues
- Shock and multi-organ failure
- Risk of death
Diagnosis
- Nucleic Acid Amplification Tests (NAAT), primarily RT-PCR, are the gold standard for diagnosis.
- Rapid antigen tests are more accessible but less sensitive; negative results may require further testing if disease is highly suspected.
Vaccination
- Vaccines include a primary series and booster doses.
- Vaccination induces both humoral (antibody) and cellular immunity.
- Reduces both the risk of contracting and transmitting the virus.
- Provides significant protection against severe illness and mortality.
Treatment Options
-
Antiviral Medications:
- Remdesivir
- Nirmatrelvir-ritonavir
- Molnupiravir
- Antibody-based Therapies are available.
- Corticosteroids: Dexamethasone is commonly used.
-
Immunomodulators include:
- Baricitinib
- Interleukin-6 (IL-6) pathway inhibitors.
